What Tenable does

Tenable Holdings, Inc. (NASDAQ: TENB) is a publicly traded cybersecurity company that provides an AI-powered exposure management platform to help organizations identify, prioritize, and remediate cyber risks across IT, cloud, identity, OT, IoT, web applications, and AI environments. Founded in 2002 and headquartered in Columbia, Maryland, Tenable built its early reputation on Nessus, the industry-leading vulnerability scanner, and has since evolved into a platform company anchored by Tenable One, which unifies modules for vulnerability management, cloud security (CNAPP, including DSPM, CSPM, CIEM, and AI-SPM), identity security, OT/ICS security, attack surface management, web application scanning, and patch management. The platform is orchestrated by Tenable Hexa AI, an agentic AI engine using the Model Context Protocol, and grounded in the Exposure Data Fabric, which ingests native sensors plus more than 330 third-party connectors via the Open Partner Exchange Network (OPEN). Tenable Research publishes Tenable Research tracks 355 additional exploited-in-the-wild vulnerabilities beyond CISA KEV's 1,569 entries with a median lead time of 3.2 days; Nessus covers 110,000+ vulnerabilities; ASM map spans 5+ billion assets.

The company generates revenue primarily through recurring subscriptions, with 96% of revenue recurring, and serves more than 40,000 global customers including Fortune 500 firms, federal agencies (notably a $50M DHS IoT contract in Q1 2025), and large enterprises in regulated industries. Tenable distributes through direct enterprise field sales, a global channel network (Deloitte, Atos, eSentire, CDW), and self-serve e-commerce for Nessus and Vulnerability Management SKUs. The company's go-to-market is anchored by analyst recognition as a Leader across Gartner, IDC, and Forrester for exposure management, and most recently by strategic partnerships with Anthropic (May 2026) and OpenAI (June 2026) to embed frontier AI capabilities into the Tenable One platform.

Tenable's growth has been driven by a combination of organic product expansion and strategic M&A, having completed acquisitions including Alsid ($98M, 2021), Accurics ($160M, 2021), Bit Discovery ($44.5M, 2022), Cymptom (2022), Ermetic ($240M, 2023), Eureka Security (2024), Vulcan Cyber ($150M, 2025), and APEX (2025). With FY2025 revenue of approximately $1.02 billion, Q1 2026 revenue of $262.1 million (+9.6% YoY), and FY2026 guidance of $1.068–$1.078 billion, Tenable is operating at scale with strong free cash flow generation (33.8% of revenue in Q1 2026) while transitioning to a platform-led, AI-native exposure management model.
